I-Polyvinyl Alcohol PVA 2488

I-Polyvinyl Alcohol(PVA) 2488 iyibanga elithile le-PVA, futhi ukuqokwa kwezinombolo kuvame ukukhombisa ukucaciswa okuthile noma izici zaleli banga elithile. I-PVA iyi-polymer yokwenziwa ekhiqizwa yi-hydrolysis ye-polyvinyl acetate. I-PVA 2488, njengamanye amabanga e-PVA, yaziwa ngokuncibilika kwayo emanzini kanye nezakhiwo zayo zokwenza ifilimu. Nazi ezinye izici ezibalulekile nezinhlelo zokusebenza ezijwayelekile ezihlobene ne-PVA 2488:

Izimpawu ze-PVA 2488:

1. Izinga le-Hydrolysis:

• Izinga le-hydrolysis ku-PVA 2488 libhekisela ezingeni lapho i-polyvinyl acetate ifakwe khona i-hydrolyzed ukuze yakhe i-polyvinyl alcohol. Amabanga ahlukene e-PVA angaba namazinga ahlukahlukene e-hydrolysis, athinta izakhiwo zawo.

2. Isisindo se-Molecular:

• I-PVA 2488 ingase ibe nesisindo esithile se-molecular, esithonya i-viscosity yayo namandla okwenza ifilimu.

3. Ifomu Lomzimba:

• I-PVA 2488 ngokuvamile itholakala ngesimo sempushana emhlophe ukuya emhlophe.

Izicelo Ezijwayelekile:

1. Izinamathiselo:

• I-PVA 2488 ivame ukusetshenziswa njengengxenye eyinhloko ezintweni ezinamathelayo ezihlukahlukene, okuhlanganisa izinto zokunamathisela ngokhuni nezinamathiselo zephepha. Inikeza amandla okuhle nokuvumelana nezimo.

2. Usayizi Wendwangu:

• Embonini yendwangu, i-PVA 2488 ingase isetshenziswe ekulinganisweni kosayizi ukuze kuthuthukiswe amandla nokuphatha izakhiwo zezintambo.

3. Izingubo zephepha:

• I-PVA 2488 ingasetshenziswa embonini yephepha ukuze kuhlanganiswe, kuthuthukise izakhiwo ezingaphezulu kanye nokuphrinta kwephepha.

4. Izinto zokwakha:

• I-PVA 2488 ingathola izinhlelo zokusebenza embonini yezokwakha, ikakhulukazi njengesengezo ekwakhiweni kukasimende ukuthuthukisa ukunamathela nokuvumelana nezimo.

5. Ukupakisha:

• Amafilimu e-PVA, kuhlanganise nalawo asekelwe ku-PVA 2488, asetshenziswa ezinhlelweni zokupakisha ezincibilika emanzini.

6. Izicelo Zokwelashwa:

• I-PVA, ngokuvamile, isetshenziswa ezinhlelweni zezokwelapha, okuhlanganisa ukukhiqizwa kwamagilavu ​​okuhlinzwa futhi njengengxenye ekwakhiweni kwezidakamizwa ezikhishwa okulawulwayo.

7. Ama-Emulsifiers:

• I-PVA 2488, enezici zayo zokuhlanganisa, ingase isetshenziswe ekukhiqizeni ama-emulsions.

Okucatshangwayo:

1. Imininingwane Yokwenziwa:

• Ukukhethwa kwebanga le-PVA, kufaka phakathi i-PVA 2488, kuncike ezidingweni ezithile zohlelo oluhlosiwe. Amadigri ahlukene e-hydrolysis nezisindo zamangqamuzana anikeza ukuhlukahluka ekusebenzeni.

2. Ukuhambisana:

• I-PVA 2488 ivamise ukukhethwa ngokusekelwe ekusebenzisaneni kwayo nezinye izithako ekwakhiweni kanye nekhono layo lokuhlangabezana nemibandela yokusebenza efiselekayo.

3. Izincomo Zomhlinzeki:

• Ukusebenzisana eduze nabahlinzeki be-PVA nabakhiqizi kubalulekile ukuze uthole isiqondiso ekusetshenzisweni okuphelele kwe-PVA 2488 ekwenziweni okuhlukene. Abahlinzeki banganikeza imininingwane ngamasu okwakhiwa kanye nokuhambisana nezinye izithasiselo.

Kafushane, i-PVA 2488 iyibanga elithile le-Polyvinyl Alcohol enezici ezihlukile eziyenza ifanelekele ukusetshenziswa okuhlukahlukene, ikakhulukazi ezintweni zokunamathisela, izindwangu, izintambo zephepha, izinto zokwakha, nokuningi. Uma unomongo othize noma isicelo engqondweni, ukunikeza imininingwane eyengeziwe kunganikeza impendulo enembe kakhudlwana.
